Don't know the legitimacy of the poll, but i felt like i need to clarify my point of view:
Abortion when women can't afford to have a child should be illegal -> If the women can't afford the child then the state should provide a financial support or enable abandonment through orphanages (if you are concerned about economy then investments in children are always profitable).
Evident of serious birth defects -> Depending on the birth defects, if the baby cannot possibly survive the birth then i find it ethical to abort
Pregnancy caused by rape/incest -> Not the child's fault about who their father/mother is so no ethical reason to abort
women's physical health is endangered -> i support the women to make the choice for themselves if they choose abortion then i won't oppose it
